As a special anonymous signature, the blindness of blind signatures makes it to play an important role in electronic commerce. Sometimes, we need a blind signature under the multiple signers. However, to the best of our knowledge, the research on the blind signer for multiple signers is much less. In this paper, we propose a novel blind signature scheme for multiple signers based on a new secur...

Restrictive blind signatures allow a recipient to receive a blind signature on a message not know to the signer but the choice of message is restricted and must conform to certain rules. Partially blind signatures allow a signer to explicitly include necessary information (expiration date, collateral conditions, or whatever) in the resulting signatures under some agreement with receiver. Restri...

the purpose of this study is to investigate the relationship between computer experience, social skills and blind students' self-efficacy in the secondary level through tehran city schools, so 129 students were selected among tehran blind schools with accessible sampling (36 females and 93 males). the results of regression analysis showed that computer experience and social skills can pred...

This paper is devoted to blind deconvolution and blind separation problems. Blind deconvolution is the identiication of a point spread function and an input signal from an observation of their convolution. Blind source separation is the recovery of a vector of input signals from a vector of observed signals, which are mixed by a linear (unknown) operator. We show that both problems are paradigm...

In a proxy signature scheme, a potential signer delegates his signing power to a proxy, who signs a message on behalf of the original signer. In a blind signature scheme, the signee cannot link the relationship between the blind message and the signature of the chosen message. That is, the signee cannot make a linkage between the blind signature and the identity of the requester. Therefore, it ...

Scientists observe, discover, justify and eventually share their findings with the scientific community. Dissemination is an integral aspect of discovery, since discoveries which go unnoticed have no or little impact on science. Today, peer review part this process dissemination as it contributes proactively to quality a article. As numbers journals articles published therein are increasing ste...

Purpose: This paper reviews the studies on balance in blind. Methods: The comprehensively reviewed blind from following databases: PubMed, MEDLINE, Web of Science, ScienceDirect, Cochrane Central Register Controlled Clinical Trials, Google Scholar, and Scopus, 2001 to 2019. Also, other available papers were examined. Results: Out 35 evaluated studies, 32 articles fully represented rest only sum...

1 Summary The goal of blind deconvolution and source separation is to unravel the effects of an unknown linear transformation on a unknown signal source. For blind deconvolution, the transformation is a linear finite-impulse response (FIR) filter, and for blind source separation it is a matrix of mixing coefficients. A general architecture for these blind adaptive algorithms consists of an adju...

Proxy blind signature is a combination 0f both the properties of proxy signature and blind signature scheme. This scheme is useful in many applications like e-voting, e-payment and mobile agent environments. This paper presents a new proxy blind signature scheme based on discrete logarithm problem(DLP), which satisfies the secure properties of both the blind signature scheme and the proxy signa...
